Others in attendance cringed.

On Wednesday morning, boxing promoter Don King offered a spirited endorsement of Donald Trump during a speech in a largely black church in his hometown of Cleveland. Speaking while Trump watched on behind him at the New Spirit Revival Center, King at one point let a racial slur slip.

King’s case for Trump boils down to him thinking it’s important “to knock the system.” During his speech, he compared the unequal treatment of African Americans with that of women, saying both are “the left outs.”

“Donald Trump says no, we are going back to inclusiveness, everybody counts,” King said. “That’s why when I see them try to ridiculize [sic] him, or to try and ostracize and pervert, I want you to understand, every white woman should cast their vote for Donald Trump. Not for Donald Trump the man, but to knock the system, to help him to get their rights and be able to deal with it.”

Trump, who later Wednesday in Cleveland will partake in a Sean Hannity-hosted Fox News town hall focusing on on “African-American concerns,” told the crowd he invited King to travel with him.

In July, King, who was convicted of manslaughter for killing a man who owed him money on a Cleveland street in 1966 (he was later pardoned by a Republican governor), was barred from the Republican National Convention.

Trump’s outreach efforts to black communities have consisted of telling them their lives are terrible and can’t really get worse, so why not vote for a Republican for a change? During a speech Tuesday night in North Carolina, Trump said “African American communities are absolutely in the worst shape they’ve ever been in before — ever, ever, ever.”
